Seasonal hyperacute panuveitis of unknown etiology

Area of Science:

• Ophthalmology
• Medical Entomology

Background:

• A recurrent, severe unilateral uveitis causing rapid blindness has been observed in Nepal since 1975.
• The disease exhibits a cyclical pattern, typically occurring in two-year intervals during autumn.

Observation:

• Cases initially reported in Western Nepal have since spread nationwide.
• A history of contact with a white moth preceding ocular symptoms, sometimes with blister formation, was reported in some outbreaks.

Findings:

• Clinical features of the uveitis were documented.
• Laboratory experiments involving patient aqueous humor and various moth species were conducted to investigate the etiology.

Implications:

• Suggests a potential vector-borne cause for this specific type of uveitis.
• Highlights the need for further research into moth-induced ocular inflammatory diseases.
